It sounds like to me that you don't have the proper filesystem drivers built into your kernel.<BR>
<BR>
What filesystem for linux are you using?&nbsp; It needs to be built as &lt;*&gt;, not &lt;M&gt;.<BR>
<BR>
You should be using Linux naming for your hardrive in your yaboot.conf.<BR>
<BR>
Please post the output from &quot;mac-fdisk -l /dev/hda&quot; (minus the quotes please).<BR>
<BR>
Also post your /etc/yaboot.conf so we can see if that is setup correctly.<BR>
<BR>
Regards,<BR>
